Description

Technical Field

[0001] The utility model relates to the field of sand core forming molds, in particular to a protective component and a sand core forming mold. Background Art

[0002] Sand cores are the material used to create cores in foundry production. They are generally composed of a mixture of molding materials, such as foundry sand, a sand binder, and additives, in a specific ratio. The core is largely surrounded by hot liquid metal in the mold, while the supporting and positioning portions are generally small. Therefore, in addition to possessing the properties of general molding sand, core sand is also required to have high strength, air permeability, yieldability, and collapsibility. Core sand is categorized by the binder used, including clay core sand, water glass core sand, oil core sand, synthetic resin core sand, and resin core sand.

[0003] In the prior art, the production of sand cores requires the use of sand core forming molds to assist in production. Workers place the sand cores into the sand core forming molds, and the sand cores in the sand core forming molds can be taken out for use after they are solidified and formed.

[0004] However, the existing sand core forming mold lacks a protective mechanism. When the sand core is demolded, a large amount of sand core fragments are generated, which can easily cause the sand core to splash into the eyes, mouth, and nose of the operator, causing certain injuries to the staff. In addition, after the sand core is demolded, the sand core forming mold requires the staff to reach into the working range of the mold to remove the workpiece, which is dangerous and has low practicality. Utility Model Content
